Deceptive talk (4)
I believe the answer is:
jive
'deceptive talk' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for jive that I've seen before include "Jerky, jazz dance of the 1950s" , "Jerky dance of the 1940s and 1950s" , "Fast American dance" , "Jazzy dance" , "Deceptive talk" .)
